I keep on seeing CAPTCHA or re-CAPTCHA each time I will "log-in" or just clicking a tab. Does it protect a webpage? Should I need to use this whenever I create my own site? Can you show me what are the importance in providing this?
A CAPTCHA is a program that protects websites against bots by generating and grading tests that humans can pass but current computer programs cannot. It's an efficient security measure that is protecting websites from harmful viruses and anything that may jeopardize their site and information.
